To import FBX 3D models for mobile performance, optimize the model (reduce polygons, compress textures) then use a mobile-friendly engine (Unity/Unreal) and adjust settings (LODs, texture formats) to balance quality and speed.
- **Optimize upfront**: Cut unnecessary polygons (e.g., minimal subdivisions in Blender) and use mobile-optimized textures (ASTC/ETC2) to lower file size and rendering load—vital for mobile’s limited RAM/GPU. - **Use engine workflows**: Unity and Unreal natively support FBX; follow their steps (e.g., Unity’s Model Import Settings) to enable LODs (reduce detail at distance) and tweak compression. - **Test early**: Start with a simple model (small prop), use the engine’s preview, and test on target devices to catch performance issues before scaling.
